How the Presbia Corneal Inlay from Optilase Works

To understand how the Presbia intrastromal inlay works to correct presbyopia, it can be likened to a contact lens, only that it is implanted into the cornea rather than slotted in front of it.

 

The Presbia microlens is a clear disc that changes the refractive index of your cornea, so that you can clearly see objects up close. It is only suited to treat presbyopia and cannot be used to counteract any other refractive errors.

Cutting edge design

Designed to be only 3mm in diameter and only 15 microns in edge thickness (1/4 width of a single human hair), the Presbia microlens is designed to incorporate different refractive power.

 

If you think of the microlens like a ring doughnut, there is a 1.8mm central zone that does not have any refractive power, which allows for distance vision to remain largely unaffected.

 

It is the outer ring that is the refractive powerhouse, suitable for prescriptions +1.25D to 3.50D that has revolutionized near vision correction for presbyopic patients.

Biocompatible with corneal tissue

Using the latest advances in biotechnology, the Presbia microlens is compatible with the biological processes that take place in the cornea and will not aggravate surrounding tissue.

 

A 0.15mm hole at the center of the lens allows for fluid, oxygen and nutrients to flow through to maintain optimal eye health.

How the inlay works to correct vision

Far vision: Light rays pass through the central zone and the surrounding corneal tissue not covered by the lens and refracts as normal to focus on the retina. Any light that passes through the refractive peripheral area of the Presbia inlay are focused in front of the retina.

 

Near vision: Light rays that pass through the refractive zone of the Presbia inlay are focused on the retina, while those that enter the central zone will focus behind the retina. Remaining light that go through the rest of the cornea will be blocked from reaching the back of the eye by the pupil.

 

The entire procedure takes only ten minutes and sight normalizes within a few days so you can put down the reading glasses and enjoy a whole world of vision!

I had LASIK done in Dublin after a consultation and follow up in Derry. From the very start, Elizabeth in Derry put me at ease with her approach. Such a warm, helpful way about her. Surgeon Mikhall Hernandez took the time to meet me in advance to explain the process. All the staff- Iwona, Julie, Jess, Robbie (from Donegal!) and Rachael, I really appreciated the way they supported me from start to finish

I had a great LASIK experience at Optilase Carrickmines and couldn’t be happier with the results. Dr. Tom Materman is incredibly kind, attentive, and made me feel comfortable throughout the entire process. I highly recommend him, as well as the whole Optilase team! I didn’t feel anything during the procedure, which was much easier than I expected. My recovery has also been going really well—I’m only on day two, and everything has been smooth so far. Thank you to everyone at Optilase for the excellent care!

Life changing. From the initial consultation to the aftercare, Optilase have been friendly, professional and caring every step of the way. No worry or concern was too small for a detailed discussion and helpful response. 3 months after my phakic lens surgery my vision is as good as it ever was with glasses without the hassle. Would recommend the Optilase Carrickmines team to anyone.
